Hi Matrix community, 
my team have recently created a browser extension for chrome (and edge) that adds a floating “Edit” menu / tool, that hovers over your web pages, for quick access to editing in Matrix.
It adds the _admin /_edit /_nocache /_recache suffixes out of the box, but you can configure it in the settings to include any suffix you use frequently. It also has a share this page option by default.
To get it working on your website:
- Install and pin the extension
- Click the extension icon to configure it (add your website url) - it doesn’t auto detect matrix sites
- Re load the web page and the floating tool will appear
The extension won’t ever collect any data.
If you find bugs or have feature requests let me know. 
Dave.
